to temporarily release the slide does not tend to open the bearing sothat the slide can return to locking position without opening thebearing. A blow in the direction proper to open the hearing as the tubeframe is carried along by its suspension chains, will not operate torelease the slide. By this construction and arrangement, therefore, thespool journal is securely locked at all times against accidentaldisplacement and yet is capable of being released and opened by theapplication of the finger and thumb of one hand, leaving the other handof the operator free to handle the yarn spool which is a greatdesideratum in expediting the manipulation of the device.

What I claim is:

1. A journal bearing for a yarn spool or the like embracing in itsconstruction coacting pivotally connected bearing memhers combined toform a separable journalinclosing bearing and a locking detent mountedon one of said members to swing therewith and arranged in such relationto the free end of its carrying member as to be released from lookingposition by pressure in a direction toward the centre of the bearing,whereby the detent releasing pressure does not tend to open the bearing,substantially as described.

2. In a self-locking bearing for a spool journal, the combination of afixed bearing member adapted to receive the spool journal, a cooperatingmember pivotally mounted on one side of the journal and extendingforward to overhang the opposite side of the journal, a latch movabletransversely of the'journal axis and arran ed to also overhang the frontside of the journal and automatically slidable into releasableengagement with a fixed stop to positively prevent the journal fromopening the pivotally mounted journal bearing member by exertingpressure against the latter, substantially as described.

3. In a self-locking bearing for a spool journal, the combination offixed and movable journaJ-retaining members pivotally connected togetherto form a separable bearing for the reception of a journal, aself-locking latch slidably mounted on the pivotal bearing member tomove transversely of the journal axis into engagement with a fixed stopwhen the pivotal member is in closed bearing position and therebypositively but releasably lock the pivotal member against opening underpressure exerted by the journal, substantially as described.

4. In a self-locking bearing for a spool journal, the combination offixed and movable journal-engaging and retaining members pivotallyconnected to form a separable journal bearing, a spring pressed latchslidably mounted on the pivotal member in position to engage a fixedstop when the bearing closed. thereby positively locking the pivotaljournal-retaining member against opening under pressure exerted by thejournal, the forward end of said -latch being located in juxtapositionto the free end of said pivotal member to permit the latch to bereleased from locking position by the hand that opens the bearing.

5. A self-locking bearing for a tube frame spool embracing in itsconstruction a. fixed bearing member provided with an open bearingrecess for reception of a spool journal. a movable member mounted on apivotal centre beyond the closed side of the bearing recess, and havingits free end extended to overhang the open side thereof, a lockingmember carried by and slidable on said movable member transversely ofthe bearing axis with its manually operated end in close proximity tothe free end of said movable member, and a spring acting to normallypress said locking member into. positive but releasable engagement withthe fixed member to hold the movable member unyieldingly in retainingposition, substantially as described.

6. A self-locking bearing for a tube frame spool embracing in itsconstruction a fixed standard provided with a bearing recess for a spooljournal, a pivotal journal-retaining member connected therewith, aspring-pressed locking member having slotted connection with saidpivotal member to allow to and fro movement, a thrust spring arranged tonormally force said locking member into positive locking engagement withthe fixed standard while yielding under pressure to allow the release ofthe locking member to permit the journal-retaining member to move toopen position, substantially as described.

In witness whereof, I. have subscribed the above specification.
